The present invention relates to nitric oxide releasing prodrugs of known drugs or therapeutic agents which are represented herein as compounds of formula (I) wherein the drugs or therapeutic agents contain one or more functional groups independently selected from a carboxylic acid, an amino, a hydroxyl and a sulfhydryl group. The invention also relates to processes for the preparation of the nitric oxide releasing prodrugs (the compounds of formula (I)), to pharmaceutical compositions containing them and to methods of using the prodrugs.
The present invention relates to antibody-drug conjugates comprising (i) an antibody or antigen-binding fragment thereof, (ii) a polymer comprising a particular repeat unit comprising an amino acid derivative, which is covalently bound to one or more biologically active moieties, such as small molecule drugs, optionally via a linker, and (iii) a polymer-antibody linker moiety which is covalently bound to both the polymer and the antibody or antigen-binding fragment thereof. Additionally, the present invention relates to pharmaceutical compositions comprising the antibody-drug conjugates and to use of the antibody-drug conjugates in medicine.
